Nontherapeutic laparotomy in combat casualties.

Area of Science:

• Trauma Surgery
• Military Medicine
• Surgical Outcomes

Background:

• Selective nonoperative management (SNM) of ballistic abdominal injuries is controversial, especially in military contexts.
• Traditional military practice often favors broader surgical exploration over SNM.
• The risks and incidence of nontherapeutic laparotomy (NTL) in military casualties are not well-established.

Purpose of the Study:

• To determine the incidence and complications of NTL in UK military personnel who sustained battlefield abdominal trauma.
• To compare characteristics and outcomes of patients undergoing therapeutic laparotomy (TL) versus NTL.

Main Methods:

• Retrospective review of UK military patients undergoing laparotomy for battlefield trauma from the UK Joint Theatre Trauma Registry (March 2003-March 2011).
• Classification of laparotomies into TL and NTL groups.
• Comparison of demographics, physiological status, injury patterns, and mortality; complications in the NTL group were specifically assessed.

Main Results:

• 130 laparotomies were performed (7.2% of 1,813 casualties), with 103 (79.2%) classified as TL and 27 (20.8%) as NTL.
• No significant differences in demographics, injury mechanism, severe extra-abdominal injury, overall injury severity scores, or mortality between TL and NTL groups.
• Patients undergoing TL were more likely to be hypotensive and have reduced consciousness levels.
• NTL was associated with a complication rate of 25.9% (7 of 27 patients).

Conclusions:

• Trauma laparotomy has become less common, with a low NTL rate in this military cohort.
• The low NTL rate may reflect increased use of SNM or limited applicability of SNM in military injuries.
• NTL carries a significant risk of complications and should be minimized while ensuring life-threatening intra-abdominal injuries are not missed.
